“…According to the plot (Fig. 4) [1,14]. This restruc turing removed the strike-slip border between the North American and Eurasian plates in the Bering Sea, and the entire region of the Bering Sea was incor porated into the new lithospheric plate, which caused the termination of the Aleutian crust subduction under the Bauers Arc.…”

“…It is separated from the Pacific Ocean by the Aleutian island arc and consists of three oceanic basins: the Aleutian, the Commander, and the Bauers, the dividing Shirshov and Bauers aseismic submarine ridges, and the big Bering continental shelf that joins the Asian and North American continents. According to the seismic data of the current structure, the Bering Sea with the Aleutian island arc, southwestern Alaska, the coastal zone of the Koryak Upland, and Chukotka are a part of the Beringiya small lithospheric plate [1] ( Fig. 1, the inset).…”

Abstract:Based on the analysis of changes in the stress-strain state of the crust at the boundary of the Eurasian and North American tectonic plates, we develop a dynamic model of the main seismogenerating structures in Northeast Asia. We have established a regularity in changes of geodynamic regimes within the interplate boundary between the Kolyma-Chukotka crustal plate and the Eurasian, North American and Pacific tectonic plates: spreading in the Gakkel Ridge area; rifting in the Laptev Sea shelf; a mixture of tectonic stress types in the Kharaulakh segment; transpression in the Chersky seismotectonic zone, in the segment from the Komandor to the Aleutian Islands, and in the Koryak segment; and crustal stretching in the Chukotka segment.

“…The peninsula is situated at the northern terminus of the Kuril-Kamchatka subduction zone and where the Komandorsky Island block, moving parallel to the Aleutian trench, impinges on the Kamchatka mainland (Seliverstov, 1998(Seliverstov, , 2009. The region to the north of Kamchatsky Peninsula is interpreted to be the boundary between the Okhotsk and Bering plates (Lander et al, 1996;Mackey et al, 1997;Cross and Freymueller, 2008;Fig. 1).…”

International audienceKamchatsky Peninsula lies within a complex meeting place of tectonic plates, in particular, the orthogonal interaction of the west-moving Komandorsky Island block with mainland Kamchatka. Examining the Holocene history of vertical deformation of marine wave-built terraces along the peninsular coast, we differentiated tectonic blocks undergoing uplift and tilting separated by zones of stable or subsided shorelines. We analyzed ∼200 excavations along >30 coastal profiles and quantified vertical deformation on single profiles as well as along the coast using paleoshorelines dated with marker tephras. For the past ∼2000 yr, the average rates of vertical deformation range from about -1 to +7 mm/yr. Uplift patterns are similar to those detected from historical leveling and from mapping of the stage 5e Quaternary marine terrace (ca. 120 ka). Average vertical deformation in the Holocene is highest for the shortest studied time period, from ca. A.D. 250 to 600, and it is several times faster than rates for marine oxygen isotope stage (MIS) 5e terraces. Vertical displacements observed along the coast are most likely coseismic and probably have included subsidence as well as uplift events. Because subsidence is generally associated with erosion, almost surely more prehistoric large earthquakes occurred than are recorded as topographic steps in these terraces. We suggest that the distribution of coastal uplift and subsidence observed along the Kamchatsky Peninsula coastline is qualitatively explained by the squeezing of the Kamchatsky Peninsula block between the Bering and Okhotsk plates, and the Komandorsky Island block
